Your Heart Has The Answer
Your mind's fears can seem terrifying, but always remember that all fear is an illusion. Your heart is the part of yourself that is always aligned with truth and is where you'll find stillness.
Peace can always be found within your heart, regardless of what your mind tells you. When your mind is terrified, focus all your attention on your heart until the fear goes away on its own.
It's impossible to use your mind to get rid of its own fear. The answer always lives in your heart, but your mind will be tempted to try and find a solution to your fear, which can keep you stuck in it.
